[gmx-users] Secondary structure not visible after convertingfrom .gro to .pdb

[bharat gupta]

I am not concerned about secondary structure changes. But I want to
visualize the entire protein structure in ribbon form after energy
minimization... When I see the converted structure (.gro to .pdb) in pymol,
only one chain is visible. How can I see all the chains together
